01 The session in one read

The Ibovespa fell 1.73% on Friday to close at 172,513.42 points, shedding 3,032.94 points in a single session. It was the fourth consecutive daily loss and left the index down 3.08% across the week, the poorest five-day run since May.

The shape of the day tells the story. The index opened at 175,546.36, reached 176,116.84 in the first hour as investors welcomed Petrobras results, then sold off all afternoon to finish at 172,513.42, barely 380 points above its low of 172,131.20.

The currency went the other way. The dollar eased 0.46% to R$5.0836, a third straight session of gains for the real, though over the full week the American currency still finished 0.26% higher.

What made the session unusual was the contrast with New York. Wall Street rose—the Dow added 0.28%, the S&P 500 gained 0.62% and the Nasdaq jumped 1.30%—while São Paulo went the opposite way.

02 The day’s numbers

The index is now a long way from its peak. From the record close of 198,657 on April 14 to Friday’s 172,513.42 is a fall of 26,143.58 points, or 13.16%, by The Rio Times’ calculation.

That still leaves the market well above where it started this run, some 29.6% above the 133,151 low. The 180,000 mark, comfortably held only a week ago, is now more than 4% away.

03 Why it moved — a weak American jobs report and a wave of profit-taking

The session turned on a number released in Washington before the Brazilian market had properly opened. United States employers shed 23,000 jobs in July and the previous month’s figure was revised down, a genuinely weak report.

Counterintuitively, that was good news for American shares and bad news for Brazilian ones. Weak jobs data reduced the odds that the United States central bank raises interest rates next month, and investors responded by pushing money back into New York—particularly technology—and pulling it out of emerging markets.

The flow numbers back that up. Foreign investors, who make up more than 60% of trading volume on the Brazilian exchange, had already withdrawn R$834 million through 5 August.

Then came the Petrobras problem. The company reported second-quarter net income of R$52.4 billion, up 96.8% on a year earlier and comfortably above the R$50.8 billion analysts expected, the third-largest nominal profit in its history.

The shares rose more than 2% at the open and then reversed hard. The board approved R$17.4 billion in shareholder payments but no extraordinary dividend on top, and after a strong July run that was enough for holders to take profits.

Banks compounded it. The financial sector index fell 2.42%, and with Vale, Petrobras and the big banks making up roughly half the Ibovespa, there was nowhere for the index to hide.

04 The day’s movers

Fleury, the medical diagnostics group, was the standout on the upside, climbing 9.73% to R$18.95 after quarterly figures that analysts described as operationally strong with controlled debt. It was one of only a handful of shares in the index to finish higher.

At the other end, Lojas Renner dropped 8.09% to R$12.39 after cutting its projections for the year alongside weaker second-quarter numbers, and Magazine Luiza also fell after results that disappointed. Vale traded around 1% lower through the afternoon as iron ore stayed flat, adding to the weight on the index without being the main culprit.

05 The regional scoreboard

Brazil was the clear regional laggard. Mexico’s IPC was the mirror image, rising 0.82% to 66,938.64 as the same American jobs report that hurt São Paulo helped a market far more tied to the United States cycle.

Chile’s IPSA slipped 0.16%, pausing after a week that still ended 2.18% higher and left the index near its best levels since April. Argentina’s Merval fell 0.45% to 3,086,784.54, a sixth consecutive decline that has taken it back to where it traded in early June. The live market board above carries the verified closes for every regional index.

06 The technical picture

Friday’s close of 172,513.42 sat barely 380 points above the session low, which is rarely a sign of buyers stepping in late. The index has now spent four sessions giving back the ground it gained through late July.

The long rising line that has guided the index higher since late last year now runs directly beneath the current level, which makes the 172,000 area the one to watch. Below that, the next obvious floor is the 170,000 region, a level last seen in May, while 180,000 has become the barrier on the way back up.

07 What to watch

• Brazilian inflation: July consumer price figures are due next week and a soft reading would give local buyers their first clear reason to step in.
• Foreign flows: Overseas investors drive more than 60% of turnover, and August has so far been a month of withdrawals rather than purchases.
• Oil and the Strait of Hormuz: Crude slipped on Friday as talk of a reopening deal resurfaced, and Petrobras moves with it.
• The remaining earnings: Results season is still running, and Friday showed how sharply the market is punishing any company that trims its outlook.

Frequently Asked Questions

What is the Ibovespa?

The Ibovespa is Brazil’s main stock index, tracking the largest and most-traded companies listed on the B3 exchange in São Paulo.

Why did Petrobras shares fall after such a big profit?

The company beat expectations but announced no extra dividend beyond the R$17.4 billion already planned, and the shares had already run up in July. Investors who bought ahead of the results took their money off the table.

What did the United States jobs report have to do with Brazil?

When American jobs data comes in weak, global investors tend to pull money out of emerging markets and put it back into United States shares, especially technology. Brazil is on the losing end of that shift.

Why did the real strengthen while the stock market fell?

They respond to different things. The dollar weakened against most currencies after the jobs report, which lifted the real, while the money leaving the Brazilian stock market was a separate flow.
